ing nofthreaded parts; sixth, to provide a filter thatv may be furnished with or without a. 'shu't off valve without changing the design of'any of the individual parts; and seventh, to provide afilter having a removable re- I. attain these ob ects by the mechanism illustrated in the accompanying drawing, in'which -"Figure 1 is a vertical section of the entire filter; Fig.2, a horizontal section of the filter on the line 2-2, Fig. 1, without the sedi- -ment bowl and shut ofi valve; Fig. 3, a .ver-

tical section of the filter body on the line 3 Fig.1; Fig; 4, a side'view of the sediment receptacle; Fig. 5,.a' plan view of the sediment'receptacle; Fig. 6, a plan view of thetshutofl' valve plate; Fig. 7, aside view of. the shutoff valve plate; Fig. 8, an end viewi-of the valve gasket; Fig. 9, a plan view of. the valve gasket; Fig. 10, a developed view of one of the cams on the head; and Fig. 11, a developed view of one of the cams on the head. I v Similar' numerals refer to similar parts throughout the several views. j

The filter body 1 is provided with a threaded extension 2 for, attaching to a suitable supporting unit, such as a vacuum tank, and aboss 4: having a tapped hole 5 for at Theifilter head 1 is provided with the hole 6 through which the gasoline may flow into the glass receptacle 7 The receptacle 7 is 50, provided with extensions '8 which engage -Fig. 10. The receptacle? is'provided with wall of the bow1'7 Spaces 15' may be left tachment'with a gasoline line connection.-

cam surfaces 9 on the inside of'the lower por tion of the filter head 1. A filtering screen 10 fits within the filter head 1 and covers the hole 11in the filter body 1, the hole 1 1 forming the exit passage for the gasoline as it flows from the receptacle 7 through the fil-' '55 ter screen 10 and out through'the tapped hole 5. A gasket. 12 also fits within the till-- ter head 1 adjacent the filtering screen- 10 The filter head 1 is further providedwith recesses 13 through which the extensions 8 may pass. As thereceptacle is revolved, the extensions-'8 engage the cam surfaces 9 and force the receptacle? upwardly, thus com-' pressingthe screen lO'a-ndthe gasket 12 to-f ward the filter head 1, the gasket 12forming a tight joint between the filter head 1 and the top of the receptacle 7. One of the cam sur-. faces 9is shown in a developed position in portions 14- forming handholds to prevent. the operators hand from slipping thereon.

These handholds may be, if desired, raised," V

sunken, or knurledportions on the outside betweenthe portions lto permit the sedi- 5 ment in the receptacle'7 tobe readily ob-'1 served, if glass is used or to better provide for hand holds. The filter head 1 is fur ther provided with a chamber 16 having cam surfaces 17 ,oneof which is shown in .a de-. veloped position inFig. 11. It is to be noted that the'cam surfaces 17 have their angle of inclination disposed. oppositely from the angle of the cam surfaces 9. The shut ofi valve plate18 is provided with extensions or fingers 19 which are adapted to engage the camsurfaces 17 vThe filter head 1 is also 2 provided withfrecesses' 20 through which the extensions 19 maypass. As the shut offgplat'e 18 is turned, the extensions, 19 engage the camsurfaces 17 V and forcethe shut off valve plate 18 upwardly thus compressing the gasket 21 againstthe surface .22 of the filter,

'head '1, thus completely covering the hole 6 and. shutting Us the fiow .of the gasoline therefrom. The shut off valvefplate 18 is operated by means of the extensions 23v on the receptacle 7 engaging the slots 24 of the shut off valve'plate'18; The shut off'valve 'plate '18 is also provided with lugs 28 for 1103.

retaining the gasket 21 in place. When it becomes necessary to remove the receptacle 7,.it is grasped firmly by the portions 14 and revolved. This causes the extensions 8 to 7 travel down the cam surfaces 9 which gradually removes the compression from the gasket 12. During this operation the shut oli valve plate 18 is being revolved and this causes the extensions 19 to travel up the cam surfaces 17 on the filter head 1, thus gradually compressing the gasket'21 against the surface 22. It is to be noted that the cam surfaces 9 and 17 will be located with respect to each other so that the shut 03 valve plate 18 will bring the gasket 21 up to the surface 22 in the first few degrees of rotation for removing; the receptacle 7 As the receptacle 7 is further revolved to allow'the gasoline in the hole v6. When the receptacle 7 is replaced in thestrainer head, the eXtenextensions 8 to be removed through therecesses 13 the gasket 21 will be compressed suficiently to completely shut of: the flow of sions Sare passed through the recesses 13 and simultaneously the extensions 23 on the inside of the receptacle 7 are'placed in engage" line through the hole 6 by releasing the com- 'pression 0111 the gasket 21. flhegasket 21 may be made of'suiiicient resiliency to allow for any necessary amount of partial rotation of the receptacle 7 after the gasket 21 first touches the surface 22. Thusthecam sur face 9 may be developed so that the gasket 21 willcontact with the surface 22- very quicklyas the receptacle 7 is'started to revolve out of the strainer head ,1, the balance 7 r of the rotation ,iresultmg in a'steady com pression of the gasket 21. This process wouldbe reversed when the receptacle is replaced in the filter head 1, thus. delaying the removal of compression on the gasket 21' until the receptacle 7 has established a tight "jointby compressing the gasket 12. V g It is to be noted that the filtering screen 10 has a flange 25 which presses over the outside Walls of the recess 16; The gasket 12 may be suitably attached tothe filtering screen 10; This allows the diameters of'thesetwo parts to be of such-size as will permit'of easy assembling-through the mouth of the filter head 1. I The filterhead 1 may be cast withsmall lugs 26-for preventing the shut off valve plate 18: from fallingor working out through the openings- 20 when the receptacle 7 is removed from the filter head 1.

'Tlie cam surfaces 9 and :17 may be provided with a dwell" portion 27 for maintainingthe bowl 7 and the shut off plate 18 in a locked position.

It is to beunderstood that the receptacle 7 and the filter head 1 may be utilized as a lter without the shut ofl' plate 18 where a more economical unit is desired.
